How to change the batteries in your DSC key fob (remote)

Following is a step by step guide to replacing the batteries in the key fob for your ADT alarm system.

Step 1 Unclip belt clip from key fob or remove from key ring.
Step 2

To remove the key fob cover, use either:

  • the pointy end of the belt clip
  • a 10 cent piece
  • a small flat screwdriver

Give it a twist and the key fob cover should pop off.

Caution:

  • Keep the cover in a safe and clean place
  • Be careful not to damage / scratch the cover
Step 3

Using a small Philips screwdriver, remove the screw.

Caution:
Keep the screw in a safe and clean place
Step 4

Using the screwdriver as a lever, VERY gently flick the green circuit board up.

Caution:

  • Keep the circuit board in a safe and clean place
  • Be careful not to damage the circuit board by using excessive force
Step 5

Remove old batteries and dispose of safely.

Important:
Before fitting the new batteries, wait at least one (1) minute to ensure the low battery state is cleared
Step 6 Ensure the contact strip stays in place.
Step 7

You will need two3v circular CR2032 or CR2025 batteries.

Insert new batteries per the diagram inside the key fob i.e
1 x “+” = positive
1 x “-“ = negative

The positive side has the “+” symbol on it and negative side is the side without the “+”.

Caution:
Ensure they are they right way up!
Step 8

Gently press circuit board back into place taking care not to bend it too much.

Caution:
Be careful not to damage the circuit board by using excessive force
Step 9

Reinsert the screw using the Philips screwdriver taking care not to over tighten.

The screw’s function is to keep the contents in place should the cover accidentally pop off so should not be too tight.

Be careful not to damage the screw by over tightening
Step 10 Clip cover back on and gently squeeze both ends to ensure it is safely on.
Step 11 Reattach to belt clip or key ring.
Step 12 Ensure the key fob is working by pressing the set / unset button.
